SAND-LINE AND PUMP OR BAILER CONNECTION.

SPECIFICATION forming part of Letters Patent No. 679,889, dated August6, 1901.

Application filed August 16, 1900. Serial No. 27,084. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES I. DORN, a citizen of the United States,residing at Bardsdale, in the county of Ventura and State of California,have invented a new and useful Sand-Line and Pump or Bailer Connection,of which the following is a specification.

The object of this invention is to provide a superior, cheap, and simpleconnection for connectingasand-line with a pump or bailer for use inoil-wells and other bored Wells. My invention is specially designed forusing the sand pump and the bailer in the drilled or bored well belowthe bottom of the partially-inserted well-casing.

During the operation of boring and drilling oiLwells the bottom of thecasing may be anywhere from one foot to five hundred feet or more fromthe bottom of the Well, and heretofore great inconvenience and loss havebeen involved through the catching of the sand-line connection on thebottom of the well-casing, whereby the sand-line is often broken, thusleaving the sand-pump or bailer, as the case may be, at the bottom ofthe well, from which it must, if possible, be fished out at greatexpense of time and labor. This accident with the appliances now in usefrequently causes the total loss of valuable wells.

It is an object of my invention to avoid this trouble and also toprevent the detaching of the bailer or sand-pump by reason of theunscrewing of the nut or bolt which supports the bailer or pump.

These objects are attained by the cheap and simple appliance hereindescribed and claimed.

The accompanying drawings illustrate my invention.

Figure I is a perspective view of my newlyinvented sand-line and pump orbailer connection. A fragment of the sand-line is shown and also afragment of the bail of the sand-pump or bailer. Fig. II is alongitudinal section of the same along the axis of the bolt.

The connection ct is provided at one end with a tubular shank l and atthe other end with two arms 2 3, projecting therefrom in the form of a Uand perforated at 4 5 to receive a bolt b.

6 indicates a lug or shoulder on the outside of one of the arms toproject upward above the perforation t through said arm 2. 7 indicates acorresponding lug on the outside of the other arm above the bolt hole orperforation 5 in said arm. The bolt 1) is inserted through the arms andis provided with a head 8, which fits against the under side of one ofthe lugs 6. 9 indicates the nut of the bolt screwed on the other end ofthe bolt beneath the lug 7 on the other arm. The lug 7 on the other armis close to the perforation 5, at a distance therefrom sufficientlygreat to allow the nut to be turned.

0 indicates a fastening, of Babbitt metal,

molded in the tubular portion of the shank 1 around the wire rope orcable, which is held in place in the socket formed by the tube 1. Inmanufacturing the connection the body portion (indicated by a) willpreferably be formed of a forging having a cylindrical stem on at itsupper end, from which stem the lugs or shoulders 6 7 slope downward andoutward to a width equal to the length of the bolt which is to retainthe hail of the bailer, thus to form guards for the bolt and nut. Thetube 1 will consist of a pipe fitted upon the cylindrical stem or," andwelded thereon, leaving a sufficient portion of the tube projectingabove the stem a to form a socket into which the rope at will beinserted, and the Babbitt-metal fastening a will be poured to hold therope. It is to be understood that the length and thickness of the tubeand stem can be varied to increase the strength to any extent desired.

The lugs or shoulders 6 7 slope outwardly away from the tube andterminate abruptly above the perforations 4 5, so that the bolt, withits nut, will not strike against the inwardly-projecting lower ends ofthe sections of the casing at the jointswhen the sandpump or bailer isbeing drawn up.

Inpractice the attendant will hold the appliance in position with thearm 8 nearest him, so that he can insert the bolt readily through fromthe side nearest the hole, thus bringing the nut on the side next theattendant. The head 8 of the bolt fits against the shoulder 6, and thebolt is thus prevented from turning without further attention upon thepart of the attendant, who will then screw ICO the nut 9 home underneaththe lug or shoulder 7.

In Fig. I, 10 indicates a fragment of the bail of a bailer or sand-pump.

When the sand-pump or bailer is being drawn out of the well, the lugs orshoulders 6 7 prevent the nut or bolt from striking the bottom of thecasing or the joints thereof, and thus prevents the nut or bolt frombeing unscrewed or broken off.

What I claim, and desire to secure by Letters Patent of theUnitedStates, is-- 1. A sand-lineand pump or bailer connection provided at oneend with a tubular shank, and provided at the other end with two armsperforated to receive a bolt; a lug on the outside of one of the arms toproject outward above the perforation through said arm; a lug on theoutside of the other arm above the bolt-hole; a bolt inserted throughthe arms and provided with a head which fits against the under side ofone of said lugs; and a nut screwed on the other end of the boltbeneaththe lug on the other arm, said lug on the other arm being close to theperforation and at a distance therefrom sufficiently great to allow thenut to be turned.

2. A sand-line and pump or bailer connection provided at one end with atubular shank, and provided at the other end with two arms perforated toreceive a bolt; a lug'on the outlike sloping lug on the outside of theother 5 'arm'above the bolt-hole; a bolt inserted through the arms andprovided with a head which fits against the under side of one of saidlugs; and a nut screwed on the other end of the bolt beneath the lug onthe other arm, said lug on the other arm being close to the perforationand at a distance therefrom sufficiently great to allow the nut to beturned.

3. A sand-line and pump or bailer connection comprising a shank providedat its upper end with a tube and at its lower end with arms which areperforated for holding a bolt and are furnished between the tube and theperforations with shoulders which slope outwardly away from the tube andterminate abruptly above the perforations, substantially as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, at the city of Bakersfield,California, this 9th day of August, 1900.

CHARLES I. DORN.
